The Tiber is a mechanical timepiece, inspired by the functionally elegant dive watches of the 1950s and 1960s. The Tiber is a diver’s watch. It is waterproof to 200 meters, constructed from stainless surgical steel, and features a high grade sapphire crystal for excellent scratch resistance. It features Swiss Superluminova filled markers and hands for superior low light vision. The dual crown design allows you to use the upper crown to rotate the internal bezel for timing your dive, your run or how long your steak has been on the BBQ.
